All about Gruen

[Fred]

This one is measuring 10.5L (per seller). Appears to line up; not the usual click style.

Interesting, thanks for the link! Sometimes its hard to know if the description is accurate as far as size from a seller.

This one i do have faith in. I requested and kindly received permission from Cort aka 4th Dimension @ nawcc to post these photos.

His comment on the size, "measures 25.7mm", which matches up with my estimate of mine in question.

My thoughts exactly on seller measurements. However, Cort’s example makes actual sense. Good find! And center seconds, at that.

But back to my measurement, which I think i already explained but no I haven't taken the movement out of the case, but as previiusly pictured i used calipers to measure "25mm from here to there" I know very scientific. But thing is, I have orphaned confirmed 10.5 ligne movement and orphaned confirmed 11.5 ligne movement, and I used those also to size up my movement.
For the record,, for now it really is looking like around 11.5 ligne movement.
